Krzysztof Klęczar, governor of the Małopolskie region, of which Kraków is the capital, said that 15 people injured in the incident were being treated in six hospitals across the city.
The condition of 14 patients was stable, he said.
The seriously injured officer, who took part in the operation to stop the attacker, has been brought out of a coma. His condition has not improved significantly since Sunday.
The second police officer injured during the shootout was in a stable condition.
"We all hope his health will steadily improve, although his condition is still classified as serious," Klęczar said.
The governor also confirmed that the 24-year-old attacker had died in hospital shortly after 4:30 a.m. on Monday.
Police stopped attacker within minutes
Klęczar outlined the timeline of the emergency response, saying municipal police officers arrived at the scene two minutes after the first report, followed by a police patrol in the third minute.
It was the first of 30 police patrols sent to the main market square, he said.
The attacker was stopped within the next three minutes, following an exchange of fire with officers.
Firefighters, ambulance crews and an air ambulance also arrived within the first six minutes.
The governor said the response demonstrated the effectiveness and high level of preparedness of the emergency services.
Bartosz Grodecki, head of President Karol Nawrocki's National Security Bureau (BBN), also praised the police officers who intervened, saying they had shown exceptional courage in stopping the attacker.
He thanked witnesses who rushed to help the injured, as well as firefighters, paramedics, doctors and nurses.
Grodecki wished the two injured officers a speedy recovery and said providing them and their families with the necessary support was the state’s responsibility.
Prime Minister Donald Tusk also praised the officers, identifying them as Senior Constables Jakub Kulik and Artur Morański and saying they had saved many lives.
The 6th Airborne Brigade, named after Gen. Stanisław Sosabowski, has appealed for blood donations for the seriously injured officer.
Authorities urge public calm
Operations at Kraków’s main market square and the surrounding streets ended on Sunday evening, and the area was reopened to residents and visitors.
Klęczar urged the public to avoid speculation and comments that could increase social tensions.
He also warned about false information circulating online, including claims that emergency services had been absent during the attack.
"The attacker’s intention was to spread terror and make people feel that we are not safe here in Kraków. We are safe. The services are here and they are doing their job," Klęczar said.
The governor also praised witnesses who called for help and assisted the injured. They included local residents, people from other parts of the Małopolskie region and foreign tourists.
He said messages of solidarity had reached Kraków from across Poland, Europe and the world.
A mass for the victims and those injured was held on Sunday at St Anne’s Collegiate Church in Kraków, led by the city’s archbishop, Cardinal Grzegorz Ryś.
A solidarity march organised at the initiative of Kraków Mayor Łukasz Gibała was held on Monday evening, attended by the president and prime minister.

Regional police chief Artur Bednarek said restoring a sense of security was a shared responsibility of public institutions and citizens.
He urged people to pay attention to the behaviour of family members and discuss the safe handling of firearms and other dangerous objects.
He also recalled basic guidance for responding to an attack in a public place: run, hide and act if someone’s life or health is in danger.
He urged the public to notify emergency services immediately.
Investigation continues
The investigation into Saturday’s attack is continuing under the supervision of Poland’s National Public Prosecutor’s Office, with police and other services involved.
Klęczar said seven prosecutors were overseeing the collection of evidence and forensic material to establish the circumstances and possible motives behind the attack.
The shooting took place shortly after 3 p.m. on Saturday, when a masked 24-year-old man, identified as Michał Oksiński, drove onto Kraków’s main market square and opened fire on passers-by with an automatic weapon.
He then fled from police. When his car collided with another vehicle, he got out and fired at officers, who returned fire and wounded him.
He was taken to hospital, where he died early on Monday.
Six people were killed and 16 injured, including two police officers.
Police also found the bodies of the suspect’s parents and sister at the family's home in the south-central town of Ostrowiec Świętokrzyski.
Kraków is observing a period of mourning through November 11. National mourning, declared by presidential decree, began on Sunday and continues through Monday.
